Rule #1: Don't look at the example project's code. Figure it out for yourself.
Rule #2: Fulfill the below user stories. Use whichever libraries or APIs you need. Give it your own personal style.
User Story: I can see the weather in my current location.
User Story: I can see a different icon or background image (e.g. snowy mountain, hot desert) depending on the weather.
User Story: I can push a button to toggle between Fahrenheit and Celsius.

Use HTML5 Geolocation to get user location and then use the Dark Sky API which uses an HTTP Secure connection for the weather. Also, be sure to connect to CodePen.io via https://.
